Please be sure to read the product label of any insecticide you choose to use to get information on the personal protective safety gear you will need. In most situations, it is recommended that you wear long pants, a long sleeved shirt, closed toe shoes with socks, chemical resistant gloves, and goggles. In areas where ventilation is poor, a manufacturer may recommend you wear a mask or a respirator. We have put together two different safety kits that will make selecting the correct safety gear easier for you.

The Wood-Boring Beetle Identification Guide

What Do Wood-Boring Beetles Look Like?

Holes in your hardwoods, furniture, and other wooden structures in and around your home could be a sign of wood-boring beetles. These beetles lay their eggs in wood, then the larvae, known as woodworms, burrow their way out of the wood as they grow into adults.

There are several types of beetles that can be considered "wood-boring" including powderpost beetles, common furniture beetles, and old house borer beetles. Fortunately, they all share very similar identifying characteristics, as both adults and as woodworms.

If you suspect you have wood-boring beetles, use this guide to make a positive identification. Then, continue reading the rest of this guide for wood-boring beetle treatment options.

Adult beetles have a head, thorax, and body. They have a hard exoskeleton and wings. Beetles have six legs and antennae on the top of their heads.

Woodworms (larvae or immature beetles) look like small, fat worms. They have ridged bodies that can curl as they move.

Color

Wood-boring beetles range in color.

Powderpost beetles can be either black or rusty red as adults. Old house borer beetles are black or grey as adults. Common furniture beetles are black, brown, or rust colored as adults.

The woodworms of all wood-boring beetles have white or cream-colored bodies with dark heads.

Emergence Holes and Tunnels

Wood-boring beetles are most commonly identified by the emergence holes they leave in wood. Homeowners may see emergence holes or tunnels in wood beams, hardwood floors, wood planks, or furniture without spotting any pests.

Range

Wood-boring beetles can be found across the United States. They are commonly seen in forests and areas of high humidity.
